The Leviton line of Wireless Occupancy Sensors works in conjunction with the Wireless Wall Switch Receiver and the Wireless Self-Powered Remote Switch. These wireless products combine self-powered and wireless technologies with all-digital architecture. They are used to detect motion and keep lights on while the space is occupied. An ideal solution for retrofits and new construction.

Digital lighting control, with the ability to set timers and dimming
levels for one-time or recurring events, once required sophisticated,
hardwired digital addressable lighting interface (DALI, for short)
systems. Now such capabilities are becoming available with both easier
installation and operation. The intelligence of these products is built
into individual lamps and switches, so a central controller is no longer
necessary, and with operation via smartphone-based apps, programing
their operations is easier than ever.
